Procedure for the adaptation of the requirements to technical progress.

Procedure for the granting of component type-approval:

the application for component type-approval is lodged with the competent authority within a Member State by the manufacturer or assembler;

the competent authority component type-approves the masses and dimensions of the vehicles concerned if these meet the technical requirements of this Directive and are in line with the information provided by their manufacturer;

to that end that same authority fills out the component type-approval certificate annexed to this Directive.

The requirements concerning masses and dimensions form part of a body of 47 characteristics required by Council framework Directive 92/61/EEC, all of which must be supplied by manufacturers at one and the same time if two- or three-wheeled motor vehicles are to be able to be type-approved and placed on the Community market.
